SHEET-DELIVERY APPARATUS FOR PRINTING-=PRESSES.

SPECIFICATION forming part of Letters Patent No. 309,075, dated December91, 1884:.

(No model.)

I 0 (LE whom it may concern.-

Be it known that I, CHARLES B. MAXSON, a citizen of the United States,residing at Westerly, in the county of lVashington and State of BhodeIsland, have invented new and useful Improvements in Sheet-DeliveryApparatus for Printing-Presses, of which the fol.- lowing is aspecification.

The object of my invention is to produce an improved sheet-deliveryapparatusfor printing-presses, and especially cylinder-presses, wherebythe sheet may be delivered with its freshly-printed side upward andwithout being touched on such side by any part of the apparatus. Thisobject I have accomplished as hereinafter described, and illustrated inthe accompanying drawings, in which-- Figure l is a side elevation of myapparatus, showing it applied to a printing-press. Fig. 2 is a plan ortop view thereof. Fig. 3 is a detail longitudinal section of the same.

Similar letters indicate corresponding parts.

The letter A designates the press-frame, constructed to support therevolving impressioncylinder B and the type-bed O in proper relation toeach other.

D indicates a spur-wheel arranged on a shaft, D, to engage a horizontalrow or series of studs, 0, on a pendent portion of the bed alternatelyabove and below the plane of the studs, for imparting the proper motionto the bed; and B, Fig. 2, denotes a cog-wheel arranged on the shaft ofthe cylinder to gear with a driving-shaft, B for imparting the propermotion to the cylinder. 7 In a suitable cavity of the cylinder B arearranged the usual grippers, B, for holding the sheet to be printed onthe cylinder, these grippers being opened and closed by trip-pins B,acting on a cam, B of the gripper-shaft. The cylinder B makes tworevolutions during a complete traverse of the bed in both directions,and to adapt the grippers B to such motion of the cylinder the trip-pinsB are alternately thrown out of action by means of a cam, B, andeam-levers B, the whole eonstituting a press of well-known construction.

To one of the longitudinal edges of the bed 0 is secured a rectilinearrack, F, which gears with a circular rack or wheel, F, adjacent to oneend of the cylinder B, so thatin the operation of the bed a rotarymotion is imparted to the circular rack in reverse directions by meansof the rectilinear rack. The circular rack F turns independently of thecylinder B in suitable guides, or, if it be a wheel, on theoylinder'shaft, and it gears with a pinion, F", on one end of a spindle,G, on which are mounted a series of reels, G, having connected theretoone end of a series of tapes, H, which thence extend over pulleys I of acan riage, I, and the other end of which is connected to a fixed part ofthe machine, so that if the tapes are wound on the reels they act on thecarriage with a tendency to draw it inward toward the reels.

In the example shown, the reel-spindle G has its bearings in rods J J,which are connected together by a cross-bar, J, constituting the fixedpart, to which the proper end of the tapes H is connected, these rodsbeing properly arranged on the press-frame to guide the tape-carriage I.The tapecarriage I comprises two slides, which are fitted on theguiderods J J, and are connected together by the spindle I of thepulleys I. Each of the carriage-slides is exposed to the action of aspring, K, having a tendency to impel the carriage in a direction awayfrom the cylinder, so that if the tapes H are free to wind off from thereels G the carriage takes the outer position. (Shown in Figs. 1 and 2.)

The position of the tape-reels G in relation to the cylinder B is suchthat as the printed sheet leaves the cylinder it travels onto the tapesH, and to insure its reception thereon fingers L are employed to liftthe leading end of the sheet as it is released by the cylindergrippers,as indicated in Fig. 3, these fingers being mounted on a rock-shaft, L,which has its bearings in the rods J J, and on which is also mounted alever, L engaging with a cam, L, for imparting the proper motion to thefingers. In the motion of the bed 0 the tapes H are wound on the reelsG, due to the revolution thereof by the gearing F F F andalternatelywound off therefrom by the action of the carriage-impellingsprings K. The extent to which the tapes H are thus wound on the reelsis such that the tape-carriage I is thereby brought to the innerposition shown in Fig. 3, so that if the printed sheet is then inposition on the tapes it drops through the space created by thewithdrawal of the carriage, and a suitable table being provided to catchthe sheet, the latter is delivered with its printed side upward, andwithout being touched on such side by any part of the apparatus.

The winding operation of the tape-reels G is such in relation to themotion of the cylinder 0 that the sheet is entirely received on thetapes whilethe carriage I is in its inner position, and it follows thatin the ensuing outward movement of the carriage the sheet travels withit on the tapes. \Vhen the carriageIreaches its outer position, which isthe point of delivery of the sheet, the leading edge of the sheet ispresented to grippers 0, which press said edge up against the stationaryrod 1?, Fig.

1, and J hold the sheet in position, while the carriage again movesinward to clear aproper space for the delivery of the sheet. Thesedelivery-grippers O are mounted on a shaft, 0, on which is also mounteda lever, 0 connecting with a cam, 0 by means of a rod, 0, in such amanner that the grippers are closed against the rod P, Fig. 1, at theproper period, while when the tape-carriage reaches its inner positionthe grippers are opened, as shown in Fig. 3, thus releasing the sheetand permitting it to drop.

Various modifications of my invention may be made-as, for example, theproper end of the tapes H may be connected to the carriage instead of toa fixed part of the machine, in which case the pulleys I may be omitted;and instead of the springs K a weight or any other suitable means may beemployed to impelthe carriage in an outward direction for winding thetapes off the reels.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, substantially as hereinbefore described, with theimpression-cylinder and type-bed, of the tape-reels, the tape-carriage,the delivery-tapes, and a means, substantially as described, for windingthe tapes alternately on and off the reels.

2. The combination, substantially as hereinbefore described, with theimpression-cylinder and type-bed, of the tape-reels, the tape-carriage,the tapes, the reel-spindle, the pinion of the reel-spindle, thecircularraek gearing with the pinion, the rectilinear rack of the bedgearing with the circular rack, and the impelling-springs of thetape-carriage.

3. The combination, substantially as hereinbefore described, with theimpression-cylinder and type-bed, of the tape-reels, the tape-carriage,the sheet-delivery tapes having one end connected to the reels, thenceextending over pulleys of the carriage, and having the other endconnected to a fixed part of the machine, and a means, substantially asdescribed, for winding the tapes alternately on and off the reels.

4. The combination, substantially as hereinbefore described, withtheimpression-cylinder, its gripper, and the type-bed, of thetape-reels, the tape-carriage, the sheet-delivery tapes, a means,substantially as described, for winding the tapes alternately on and offthe reels, and the lifting-fingers adapted to act on the leading edge ofthe printed sheet as it is released bythe cylinder-grippers.

5. The combination, substantially as hereinbefore described, with theimpression-cylinder and type-bed, of the tape-reels, the tape-earriage,the sheet-delivery tapes, a means, sub stantiallyas described, forwinding the tapes alternately on and off the reels, and thedelivery-grippers adapted to seize the leading edge of the sheet in theouter position of the carriage. v

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
